Juan Villarreal, Virginia Commonwealth University, Logarithmic singularities in vertex algebras
- This event has passed.
In this talk we want to consider a different kind of singularities in logarithmic vertex algebras. In vertex algebras many properties arise from the locality of their fields. In particular, this implies the expansion of their brackets into a base of delta function and its derivatives. On the other hand some examples in physics lead us to consider some non-local fields. We are interested in studying the different kind of singularities that appears in these cases.
